High-strength leather release paper treatment process

Abstract

The invention discloses a high-strength leather release paper treatment process, and belongs to the field of leather release paper. On the basis of an existing process, an embossing mode is changed, and a strength enhancing material for improving the strength of release paper is injected in embossed patterns to reduce the occurrence of sheet breakage, on one hand, the embossed patterns stretch across the breadth of the release paper, a covering range is increased while the number of the embossed patterns is reduced, so that the transverse tearability and the longitudinal tensile strength of the release paper are effectively improved; and on the other hand, the embossed patterns are communicated with one another, and after the strength enhancing material is injected into the embossed patterns, the multiple embossed patterns are connected in series into a whole, so that the mechanical strength of the release paper is effectively improved, the heat resistance and the tear resistance of the strength enhancing material are relatively excellent, the fragmentation rate of the release paper can be effectively reduced, in addition, reinforcing parts can be selectively added into the embossed patterns, and therefore, the strength of the release paper is further improved.

Description

technical field [0001] The invention relates to the field of leather release paper, in particular to a high-strength leather release paper treatment process. Background technique [0002] The release paper is a kind of anti-adhesive paper that prevents the prepreg from sticking and protects the prepreg from contamination. The release paper is made of paper coated with anti-adhesive substances, and its type should be distinguished according to the difference in material, thickness, elongation, and single-sided and double-sided. The release paper should meet the following requirements: it can stick to the prepreg, but it is easy to separate the two; it will not chemically react with the resin system or pollute the resin system; when the ambient temperature and humidity change, the length and width of the release paper should be Keep it unchanged so as not to cause the release paper to wrinkle and cause the prepreg to wrinkle; it should have sufficient compactness to prevent m...

AI Technical Summary

Problems solved by technology

[0004] Although the leather release paper is easy to use, the current release paper is generally broken, mainly because the release paper has to go through the test of high temperature for many times. Under the high temperature environment, the paper is in a dry state, and the mechanical strength decreases. Coupled with the wear and tear during repeated use, it is easy to cause the release paper to break
